What is ACV joint in a car?Constant velocity joints, commonly known as CV joints, are located at each end of the drive shaft. They connect the wheels to the axles as well as to the transmission. CV joints shift torque at a controlled speed to the wheels. They are also responsible for the up and down motions of the suspension system.
What is ACV joint?A constant-velocity joint (also called a CV joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase in friction or backlash) as the angle between the two shafts moves within a certain range.

If you drive a car with a damaged CV, the joint will disintegrate further, making driving impossible. You'll not be able to control the vehicle and may get involved in an accident.
